Argus Nanosensors Inside Plants is a groundbreaking bio-hybrid innovation that integrates nanoscale chemical sensors within living plant leaves to create an electricity-free water monitoring system. This revolutionary design employs nanometer-scale chemical-based sensors, which are precisely injected into plant leaves through pressure injection techniques, creating a sophisticated biological monitoring platform. The system utilizes DNAzyme as a sensor assay inside the leaves, incorporating double-stranded DNA that breaks into single strands upon contact with Lead (Pb2) heavy metal ions and binds to single-walled carbon nanotubes. The nanosensors, measuring approximately 2nm, remain within the intercellular space and produce a visible fluorescent glow that becomes quenched when lead impurities are detected, providing a visual indication of water contamination. This innovative approach enables continuous 24-hour monitoring of water quality, with response times ranging from 15 minutes to 2 hours, significantly improving upon traditional laboratory testing methods. The design, which won a Silver A' Design Award in the Cybernetics, Prosthesis and Implant Design category, represents a significant advancement in environmental monitoring technology, offering a sustainable solution for detecting heavy metal contamination in water systems without requiring electrical power, making it particularly valuable for monitoring river beds and water supplies in various environmental contexts.
